Display with enhanced highlights

Abstract

A display has a transparent plastic substrate and a colored image formed on the substrate. The colored image is formed on the substrate by process printing a large number of small dots, colored red, yellow, and blue, in a predetermined pattern onto the substrate. The red, yellow, and blue ink dots are translucent to visible light. A pattern of opaque white ink dots is process printed over selected portions of the image to highlight the selected portions and to thereby give the selected portions an appearance of relative depth. A reflective layer can be deposited against the ink patterns to reflect light which passes through the ink patterns and thereby give the image formed by the ink patterns a shiny, metallic appearance.

We claim: 
     
       1. A display, comprising: a transparent substrate;   a translucent first pattern of colored ink deposited on a surface of said substrate, to form an image; and   a second pattern of opaque ink dots deposited in a selected area of said image;   wherein said opaque ink dots are deposited at a selected density to create the appearance of a desired depth in said selected area of said image.   
     
     
       2. A display as claimed in claim 1, wherein said first pattern of colored ink comprises a matrix of dots. 
     
     
       3. A display as claimed in claim 1, wherein said opaque ink dots are white. 
     
     
       4. A display as claimed in claim 1, wherein at least a portion of said second pattern of opaque ink dots is deposited over at least a portion of said first pattern of colored ink. 
     
     
       5. A display as claimed in claim 1, wherein at least a portion of said second pattern of opaque ink dots is deposited over at least a portion of said image not occupied by said first pattern of colored ink. 
     
     
       6. A display as claimed in claim 1, wherein said selected density is relatively low, thereby creating the impression of a relatively greater depth in said selected area of said image. 
     
     
       7. A display as claimed in claim 1, wherein said selected density is relatively high, thereby creating the impression of a relatively lesser depth in said selected area of said image. 
     
     
       8. A display as claimed in claim 1, further comprising a reflective layer deposited against said first and second patterns of ink to reflect light through said first and second patterns, thereby giving a shiny appearance to said image, wherein said appearance is relatively less shiny in any area covered by said second pattern, and relatively more shiny in any area not covered by said second pattern. 
     
     
       9. A display, comprising: a transparent substrate;   a first pattern of colored ink dots deposited on a surface of said substrate, to form an image; and   a second pattern of opaque ink dots deposited in a plurality of areas of said image;   wherein said opaque ink dots in a first of said areas of said image are deposited at a first, relatively higher density, to create the appearance of a first relatively lesser depth in said first area; and   wherein said opaque ink dots in a second of said areas of said image are deposited at a second, relatively lower density , to create the appearance of a second relatively greater depth in said second area.   
     
     
       10. A display as claimed in claim 9, wherein said opaque ink dots are white. 
     
     
       11. A display as claimed in claim 9, wherein at least a portion of said second pattern of opaque ink dots is deposited over at least a portion of said first pattern of colored ink dots. 
     
     
       12. A display as claimed in claim 9, wherein at least a portion of said second pattern of opaque ink dots is deposited over at least a portion of said image not occupied by said first pattern of colored ink dots. 
     
     
       13. A display as claimed in claim 9, further comprising a reflective layer deposited against said first and second patterns of ink dots to reflect light through said first and second patterns, thereby giving a shiny appearance to said image, wherein said appearance is relatively less shiny in any area where said opaque ink dots are relatively more densely deposited, and relatively more shiny in any area where said opaque ink dots are relatively less densely deposited. 
     
     
       14. A display as claimed in claim 9, wherein: said first density in said first area results in approximately fifty percent coverage of said first area by said opaque ink; and   said second density in said second area results in approximately fifteen percent coverage of said second area by said opaque ink.   
     
     
       15. A method of making a display of an image which gives the impression of a first relatively lesser depth in a first selected area of said image and a second relatively greater depth in a second selected area of said image, comprising the steps of: providing a transparent substrate;   placing a first pattern of colored ink dots on said substrate to form an image; and   placing a second pattern of opaque ink dots over at least one selected area of said image, with said dots deposited at a selected density to create the appearance of a desired depth in said selected area of said image.   
     
     
       16. A method of making a display of an image, as claimed in claim 15, wherein: said second pattern of opaque ink dots includes a first selected area where said dots are deposited at a relatively high first density, to create the appearance of a first relatively lesser depth in said first area; and   said second pattern of opaque ink dots includes a second selected area where said dots are deposited at a relatively low second density, to create the appearance of a second relatively greater depth in said second area.   
     
     
       17. A method of making a display of an image, as claimed in claim 15, wherein said opaque ink dots are white. 
     
     
       18. A method of making a display of am image, as claimed in claim 15, wherein at least a portion of said second pattern of opaque ink dots is deposited over at least a portion of said first pattern of colored ink dots. 
     
     
       19. A method of making a display of an image, as claimed in claim 15, wherein at least a portion of said second pattern of opaque ink dots is deposited over at least a portion of said image not occupied by said first pattern of colored ink dots. 
     
     
       20. A method of making a display of an image, as claimed in claim 15, further comprising the step of depositing a reflective layer against said first and second patterns of ink dots to reflect light through said first and second patterns, thereby giving a shiny appearance to said image, wherein said appearance is relatively less shiny in any area covered by said second pattern, and relatively more shiny in any area not covered by said second pattern.
